Abstract
The invention discloses a kind of furnace body floss hole flue gas leakage devices, including furnace body floss hole, boiler water wall and the gap that is formed between the two, it is characterized in that, the gap is equipped with sealing device, the sealing device includes hydraulic seal device and high temperature resistant blanket, the high temperature resistant blanket is mounted on the gap location of the vertical furnace body floss hole extending direction, and the hydraulic seal device is mounted on the gap location of the furnace body floss hole extending direction.The configuration of the present invention is simple is equipped with different sealing devices in different location, and air can be entered by solving gap between furnace body floss hole and boiler water wall, and the problem of cause flue gas to leak.
Description
Technical field
The present invention relates to field of boilers, more particularly, to a kind of furnace body floss hole flue gas leakage device.
Background technique
Gap is big between bottom blowing furnace body floss hole and boiler flue water-cooling wall, during normal production, due to the presence in gap,
Large quantity of air enter, increase dust collecting system amount of flue gas emission, be not able to maintain furnace interior air pressure balance thus, cause flue gas from
Feed opening, floss hole leak.Find that furnace body floss hole positional structure haves the defects that in the following aspects after analysis.
1, furnace body floss hole and boiler water wall gap are excessive, and there are the conditions of flue gas leakage；
2, since furnace body needs to rotate and the thermal expansion amount of boiler, what gap was necessarily present；
3, east-west direction gap does not have a sealing device, and when production blocks since positional relationship cannot manually cover high temperature resistant blanket.
Summary of the invention
The technical problem to be solved by the present invention is a kind of presence for not influencing gap is overcome the deficiencies of the prior art and provide,
It can prevent air from entering the furnace body floss hole flue gas leakage device of furnace body again.
The technical solution adopted by the present invention to solve the technical problems is: a kind of furnace body floss hole flue gas leakage device,
Including furnace body floss hole, boiler water wall and between the two the gap that is formed, the gap are equipped with sealing device, the sealing
Device includes hydraulic seal device and high temperature resistant blanket, and the high temperature resistant blanket is mounted on vertical furnace body floss hole extension side
To gap location, the hydraulic seal device is mounted on the gap location of the furnace body floss hole extending direction.
Further, the hydraulic seal device includes hydraulic push rod, gasket and fixing end, and the fixing end is mounted on furnace
Body floss hole edge, described hydraulic push rod one end are connected with furnace body floss hole, and the other end is connected with gasket, hydraulic thrust
Bar pushes gasket to fixing end, and gasket is made to be connected with fixing end.
Further, the gasket includes skeleton and blanket, and blanket is surrounded by outside the skeleton.
Further, the skeleton is made of metal material, and the blanket is high temperature resistant blanket.
Beneficial effects of the present invention:
The configuration of the present invention is simple is equipped with different sealing devices in different location, solves furnace body floss hole and boiler water cooling
Gap between wall can enter air, and the problem of cause flue gas to leak.

Specific embodiment
The invention will be further described with reference to the accompanying drawings and embodiments.
Referring to Fig.1 ~ 3: a kind of furnace body floss hole flue gas leakage device, including furnace body floss hole 4,1 and of boiler water wall
The gap formed between the two, gap are equipped with sealing device, and sealing device includes hydraulic seal device 2 and high temperature resistant blanket 5,
Hydraulic seal device 2 is mounted on the gap location of 4 extending direction of furnace body floss hole, and high temperature resistant blanket 5 is mounted on vertical furnace body floss hole 4
The gap location of extending direction.
Restriction to direction for convenience, in the present embodiment, according to the installation site of furnace body, 4 side of extension of furnace body floss hole
To for east-west direction, the as installation site of hydraulic seal device 2；Vertical 4 extending direction of furnace body floss hole is North and South direction, i.e.,
For the installation site of high temperature resistant blanket 5.
It is equipped with hydraulic seal device 2 in east-west direction, hydraulic seal device 2 includes hydraulic push rod 3, gasket 21 and fixes
End 22, hydraulic seal device 2 are two, and opposing mirror image setting, the fixing end 22 of the hydraulic seal device 2 of side is mounted on furnace body
The edge of floss hole 1, the angle surrounded are 120 °, and the side of fixing end 22 is arranged in hydraulic push rod 3, connects on hydraulic push rod 3
It is connected to gasket 21, gasket 21 is pushed ahead by hydraulic push rod 3, is contacted with fixing end 22, keeps gap herein close
Packing 21 is sealed.
By being applied in combination for fixing end 22, gasket 21 and hydraulic push rod 3, gap can conveniently be carried out
It blocks, and also conveniently removes gasket 21, so that gap is opened.
Gasket 21 makes skeleton using metal material, and metal use can select steel, iron or aluminium alloy etc., this implementation
Skeleton is made using steel in example, one layer of blanket resistant to high temperature is surrounded by outside skeleton, forms gasket 21.
High temperature resistant blanket 5 is lifted in North and South direction, high temperature resistant blanket is two, and opposing mirror image setting, each surrounds angle
Degree is 60 °, and after high temperature resistant blanket 5 installs, indirect labor is tightened, and prevents flue gas from leaking.Pass through east-west direction in this way
Hydraulic seal device 2 and the high temperature resistant blanket 5 of North and South direction all seal in gap, prevent the entrance of air, it is therefore prevented that furnace
Flue gas leaks when body running.
